Issue in Publishing Power BI Report Server with Local AD

Hi PowerBI Experts,

Scenario

• Local AD is set is contoso.com for testing purposes with server domain controller with the named as DC server.
  
  
• Setting up a Power BI Reporting Server testing environment with SQL Server 2016 Enterprise Trail with server name as SPSQL
  
  
• Installed and Configured SQL Server Analysis Services (SSAS) Wide World Importer samples from GitHub.
  
• Had set up SQL Server 2016 WWI-SSADMD as shown: 
  
  
  
  
  
  
  
• • Installed and Configured latest version of Power BI Enterprise data gateway on SQL Server 2016 box itself.
    
    
  • Clicked open the Power BI Desktop (Aug 2018) version for Power BI reporting server.
    
    
  • In Power BI desktop, Get Data >> SQL Server Analysis Server database. 
    
    
    
    
  • Connect to SQL Server 2016 with SSAS database
    
    
    
    
    
  • Drag and drop City in map Visuals. 
    
    
    
    
  • File >> Publish to Power BI service with my Office 365 login credentials as [email protected]   
    
    
    
    
  • Selected the Workspace. 
    
    
    
    
    
    
  • As I have configured enterprise gateway earlier, the publishing was successful.
    
    

Challenge   

• In the Power BI URL https://app.powerbi.com I get this error.
  
  
• Under Managed Gateway, the Gateway Clusters shows that it's Online
  
  
  
  
  
• Data Sources is also successful with my Local AD accounts. 
  
  
  
  
• I mapped the uses as per Power BI documentation 
  
  
  

As I am doing Power BI Reporting Server for the first, can you please advice how can resolve my issue? 
Any help would be highly appreciated.
